I love where this is going. Maybe I'll go and buy myself one of these LG drives so I can rip my games and test GC emulation with textures replacement.
Just one question. Does this use only GPU, or CPU and GPU for the textures rendering?
It uses the CPU for converting the files to something the GPU can read, but it caches textures so there should be minimal lag when loading them.
On another note: r3190 should have the final format for loading textures implemented, but there are a handful of special cases which don't like to play nice which I plan to look at later.
If you try to dump textures, watch out for any of these three things:
* Using safe texture cache
* Using Copy EFB to RAM
* FMVs
Those can dump hundreds, possibly thousands of textures in a matter of minutes, and keep dumping them.
